Hey, I have recently bought a 40k 250 and I am having some problems with oil and coolant temps. I have the rs monitor and it keeps telling my oil temp sits around 72/73/74 degrees which is very low. The engine oil is the normal Renault elf stuff. At the same time, my coolant gauge sits like the attached. I figured out my thermostat is stuck open. However, I sat in traffic today,( 10 minutes) and it went to the notch on the right of the below and oil temp went up to 78 degrees. ( still low) Could this be the thermostat still or something else? Pictures attached of the two gauge marks. Second one being where it sits when driving. First one after 10 minutes in traffic. Thanks
